SPA504G phones failing to update Firmware

I manage a small office with approx 12 SPA504Gs I have spent time setting up correct provisioning to ensure all phones get the latest updates and this works on most phones.


However there are 4 phones in the office that are stuck on an older version. I believe this may have happened because the firmware file was moved on the provisioning host while they were downloading it a few months ago. Now they download whatever new firmware file, reboot but they're still on 7.5.5b.


How can I diagnose/resolve the issue?

Catch phone's communication. It will reveal where the device are asking, the request they are issuing as well as server's response.

In the case the SSL is used tun on syslog&debug messages and catch them. They are not as good source of information as phone's communication itself, but in most case it allow to identify issue as well.
